Restoring database from . SQL Server 2. 00. First google search yielded me this answer. So I thought of updating this with newer version of attach, detach. Create database dbname. Filename= 'path where you copied files'. Filename ='path where you copied log'. Further,if your database is cleanly shutdown(there are no active transactions while database was shutdown) and you dont have log file,you can use below method,SQL server will create a new transaction log file. Create database dbname. Filename= 'path where you copied files'. For attach. if you don't specify transaction log file,SQL will try to look in the default path and will try to use it irrespective of whether database was cleanly shutdown or not. Here is what MSDN has to say about this. If a read- write database has a single log file and you do not specify a new location for the log file, the attach operation looks in the old location for the file. If it is found, the old log file is used, regardless of whether the database was shut down cleanly. However, if the old log file is not found and if the database was shut down cleanly and has no active log chain, the attach operation attempts to build a new log file for the database. There are some restrictions with this approach and some side affects too. ![]() Restore from the ldf file in the sql server. I have only.mdf and.ldf file and I want to restore from the.ldf file from the dated 12. You can only attach a database if these two files are from the same point in. A.bak file could be either a full or differential back up. The full back up contains all the information necessary to restore the entire database, mdf, ldf, and ndf files. what are.mdf and.ldf files in SQL server? Hi VJ Shah, If you are using SQL Server 2005 and higher, then we could use the Import and Export Wizard to copy the new table's data to the old one. Here are the general steps: Right click old database, select Tasks. Microsoft's SQL Server stores its databases in.MDF files. you must restore it from its.MDF file in a process called “attachment.”. (FILENAME = ' c:\data files\my_data.ldf'). Database trustworthy is set to off. Detaching a read- only database loses information about the differential bases of differential backups. ![]() Our SQL DB server crashed last week wherein the SQL header info has crashed in.mdf file. As a result all.mdf files have become 0kb. The log files are intact and are of large size. We need a recovery tool / process. Most importantly. References: https: //msdn.
